摘要： An optical receiver module includes: a lens array including a plurality of condenser lenses arranged in one direction to define a plane with optical axes in parallel to each other; and a light receiving element array including a plurality of light receiving elements each configured to receive light emitted from each of the condenser lenses. The light receiving element array includes: a semiconductor substrate to which the light from each of the condenser lenses is input and through which the light is transmitted; and light receiving portions each configured to receive the light transmitted through the semiconductor substrate and convert the light into an electrical signal. A shift of the optical axis of each of the condenser lenses from a center of each corresponding one of the light receiving portions is larger in a direction perpendicular to the one direction within the plane than in the one direction.

摘要： Provided is an optical receiver including a first delay interferometer, a second delay interferometer, and an input light splitting portion for inputting modulated light. The first delay interferometer includes a first light splitting portion for splitting the input light into first light and second light, a first reflecting portion and a second reflecting portion for causing the first light and the second light to return to the first light splitting portion. The second delay interferometer includes a second light splitting portion for splitting the input light into third light and fourth light, a third reflecting portion and a fourth reflecting portion for causing the third light and the fourth light to return to the second light splitting portion. A region between the first light splitting portion and the second reflecting portion intersects with a region between the second light splitting portion and the fourth reflecting portion.

摘要： An optical receiver module capable of increasing the range in which the error in distance between a collecting lens and a light receiving section is allowed is provided. In the optical receiver module according to the invention, the optical receiver includes a semiconductor substrate to which the light from the collecting lens is input, and through which the light passes, and a light receiving section disposed on a side (a reverse side) of the semiconductor substrate, the side being further from the collecting lens, and adapted to receive the light transmitted through the semiconductor substrate, and then convert the light into an electrical signal. On a side (an obverse side) of the semiconductor substrate, the side being nearer to the collecting lens, there is formed a lens surface adapted to converge light from the collecting lens toward the light receiving section.
